So you're looking, at best, at a 2:1 insurance policy against, at worst, a 15% chance the IMS bearing will actually fail.
Is it worth it?
I have a 2002 with 93K miles and Tiptronic. If I had a manual and needed to change the clutch, the IMS bearing may have been a "while you're in there" sort of thing. I don't, so it's not worth it for me.

FWIW, when I installed a used motor, 78k miles, into my '03 S, I elected NOT to replace the IMSB. There are so many things that can take out these motors, it seems the IMSB has a relatively low failure rate, comparatively. (When all is taken in aggregate)
Why bother?
